In this paper we propose a path based mathematical formulation and solve it using a Branch-and-Price algorithm. We demonstrate that, unlike flow based approaches, our formulation is more easily extended to handle certain families of constraints, such as train unit maintenance restrictions. The ...
Hence, advanced algorithms are needed to solve the 2E-IRP heuristically and optimally. This paper proposes a novel exact branch-and-price algorithm for the 2E-IRP. The contributions are threefold: • We propose a mathematical model for the 2E-IRP, where customers can be visited from any ...

二、branch and price branch and price其实是column generation和branch and bound的结合。为什么要结合呢?前面的文章中介绍过,column generation是求解大规模线性规划问题的,注意是线性规划问题,不是整数或者混合整数规划问题。 因此在用column generation求解VRPTW的Set-Partitioning Model的时候,需要先将决策变量由整数松...
